SAE J30 R9 R11 R13 R14 FKM ECO Hose

The SAE J30 R9 R11 R13 R14 FKM ECO Hose is engineered for automotive applications requiring high levels of resistance to fuel, oil, heat, and environmental exposure. It can be manufactured using FKM, ECO, and other compatible rubber materials in accordance with the requirements of the intended application.

FKM, or fluoroelastomer, provides excellent resistance to fuels, oils, high temperatures, and many aggressive chemicals. ECO, or epichlorohydrin rubber, offers good resistance to fuel vapors, ozone, weathering, and automotive operating environments. Combining suitable material layers can provide a balanced solution for applications requiring fuel resistance, flexibility, and long-term durability.

The hose can feature a multilayer structure consisting of an inner fuel-resistant tube, reinforcement layer, and protective outer cover. The reinforcement can be made from textile or fiber materials to improve dimensional stability, mechanical strength, and resistance to pressure fluctuations.

Its flexible construction allows convenient installation around fuel tanks, fuel pumps, filters, engines, and other automotive components. The hose can accommodate normal vibration and movement during vehicle operation while maintaining reliable connections and fluid transfer performance.

Different specifications can be customized according to the application, including inner diameter, outer diameter, wall thickness, length, reinforcement structure, material formulation, bending angle, and connection configuration. OEM production can also be provided based on customer drawings, samples, or technical requirements.

The hose is suitable for a variety of automotive fuel and fluid transfer applications, including fuel supply systems, fuel injection-related lines, fuel filter connections, fuel pump assemblies, engine-compartment fluid lines, oil transfer systems, and other applications requiring high-performance rubber hoses.

It can be supplied for passenger cars, commercial vehicles, trucks, construction equipment, agricultural machinery, and other fuel-powered equipment.

Important Specification Note

The SAE J30 R9, R11, R13, and R14 designations cover different automotive hose applications and performance requirements, so the exact material combination, construction, temperature range, pressure rating, permeability performance, and applicable standard should be confirmed according to the specific hose type and intended service conditions. FKM/ECO material selection can then be optimized to meet the customer's application requirements.
